  • Publication number: 20240101831
    Abstract: An object to be achieved by the present invention is to provide a pigment which is comfortable and smooth to the touch in a coating, spreads well on the skin, for example, when used in a cosmetic material such as a foundation or an eye shadow, and exhibits good color development and gloss. A pigment of the present invention is a coated pigment formed by coating a surface of a flaky base material made of at least one metal or metal oxide with a colorant. The surface of the flaky base material has a coarse particle area fraction of 9% or less. Further, it is preferable that the flaky base material be at least one or more selected from the group consisting of mica, aluminum, alumina, and glass.

  • Publication number: 20240077826
    Abstract: A chute is located between a transfer roller and a fuser in a direction crossing both a first direction along a drum axis direction and a second direction crossing the first direction. The chute causes a sheet having passed through a transfer nip to be directed toward a fixing nip. The chute is movable in the second direction between a first position and a second position shifted from the first position toward one side in the second direction. The chute located at the second position is farther away from an imaginary plane passing through the nips than the chute located at the first position. A reciprocating mechanism is located on an other side of the chute in the second direction. The reciprocating mechanism reciprocates by drive force from the drive source and presses the chute to move between the first position and the second position.

  • Patent number: 10265226
    Abstract: One purpose of the present invention is to provide a water-absorbent resin having excellent water absorption characteristics and being capable of improving the shape-retaining characteristics of a water-absorbent material when used in the water-absorbent material. A water-absorbent resin obtained by performing reversed phase suspension polymerization of a water-soluble ethylenically unsaturated monomer in a hydrocarbon dispersion medium, using a radical polymerization initiator, said resin being capable of having both excellent absorption performance and shape retention in a water-absorbent material using the water-absorbent resin, as a result of fulfilling the conditions of: (1) having a water-retention capacity of physiological saline of at least 38 g/g; (2) having a water-absorption capacity of physiological saline under a load of 4.14 kPa of at least 15 ml/g; and (3) having a tan ? of a 50-fold swollen gel of at least 2.10×10?2.

  • Patent number: 9333432
    Abstract: To increase the player's expectation in a fight game using game media, the present invention provides a server device that controls a game in which a player does a fight using game media in a game space through a network. The server device includes a storage unit configured to store player information including information about the game media that the player owns in the game space and about a status of the game media; a determining portion configured to determine whether a specific game medium among the game media that the player owns has satisfied a predetermined temporal requirement; and an updating portion configured to update the player information so as to change the specific game medium from a first status to a second status when the determining portion determines that the specific game medium has satisfied the predetermined temporal requirement.

  • Patent number: 9221030
    Abstract: A method for producing a water-absorbent resin includes a polymerization step of polymerizing a polymerizable component containing a water-soluble ethylenically unsaturated monomer dissolved in water using a water-soluble azo-type radical polymerization initiator to obtain a reaction system including a water-absorbent resin precursor, and a dehydration step of removing water from the reaction system by heating. In the dehydration step, a water-soluble radical polymerization initiator is added to the reaction system at any first dehydration stage when the residual water rate calculated by the formula (1) is 50% or more, and a reducing substance is added to the reaction system at any second dehydration stage when the residual water rate decreases from that at the first dehydration stage by 10% or more. According to this production method, a water-absorbent resin having satisfactory water-absorption capacity can be produced while suppressing the content of residual monomers.

  • Publication number: 20140295973
    Abstract: In a combat type game using a network, an interchange between players is promoted. A server device that controls a game played by a player using game media in a game space through a network includes a storage unit that stores information about the game media owned by the player in the game space and about states of the game media; a medium transferring unit that transfers the game media from the player owning the game media such that the game media are owned by another player; a determining unit that determines whether a specific game medium among the game media has satisfied a predetermined transfer requirement; and a changing unit that changes, when it is determined that the specific game medium has satisfied the predetermined transfer requirement, the specific game medium from a first state to a second state and stores the changed state in the storage unit.
